consider the Maxon OD-808 as well. No experience with the Tokai pedal.

The maxon is great. I modded mine with a .1 uf cap in the tone stack (instead of .047) an easy mod that gives a touch more low end and a slightly different character... less overly midrangey but not "scooped" sounding either by any means. More of a flat response IMO.

I used it stock for about 2 years though before I modded it and it was also quite nice that way.
